How we calculate

Everything below is worked out on your device. Your location never leaves it.

Prayer times

Worked out by the adhan library with the method most mosques in your country use (Bangladesh, Pakistan, India: Karachi with Ḥanafī ʿAṣr; Saudi Arabia: Umm al-Qura; and so on). Both can be changed in Salat settings.

Your day

Starts at Fajr at your saved place by default, so night prayers and suhoor belong to the day before. Midnight or Maghrib if you prefer. Without a saved place it starts at midnight.

Hijri date

Your own adjustment comes first, then the moon-sighting record for your country (when a month was announced to begin), then the Umm al-Qura calendar.

Travel (qaṣr)

Musafir shortens four-rakʿah prayers while you are on a journey and offers to join prayers on the move, following the madhab you choose. The distance and stay rules for each school are shown there with their sources.

Kaza

When a day ends with a prayer still unmarked, it is marked Miss and added to your make-up count. Ramadan days not fasted go to your fasting make-up count. On days Rayhanah marks as excused, no kaza is added.

These describe how the app works, not religious rulings. Ask a scholar you trust about your own case.
